Step-by-step explanation:
40children - 23 (with A, O) = 17left
26 letter in alphabet- ( A, O) = 24 letter left
24 letters left - 14 (not used for 1st letters) = 10
10 letters left to use/ 17 children left
10÷17 = 0.5882352941 x 10 =5.8 or as close to 6 I can get
Answer:
a) For this case we see that the cumulative % for 600 is 77.1% so then we will have 0.771 of the values below 600
b) For this case we know that the cumulative percent for 1200 is 98.2% so then the percentage above would be 100-98.2 = 1.8%, so then the proportion above 1200 would be 0.018.
c) For this case we can add the percentages obtained from the previous parts and we got : 77.1% +1.8% = 78.9% and then the proportion that are less than 600 and at least 100 would be 0.789
Step-by-step explanation:
Assuming the cumulative percentages in the figure attached.
What proportion of fire loads are less than 600?
For this case we see that the cumulative % for 600 is 77.1% so then we will have 0.771 of the values below 600
What proportion of fire loads are At least 1200?
For this case we know that the cumulative percent for 1200 is 98.2% so then the percentage above would be 100-98.2 = 1.8%, so then the proportion above 1200 would be 0.018.
What proportion of fire loads are less than 600 at least 120?
For this case we can add the percentages obtained from the previous parts and we got : 77.1% +1.8% = 78.9% and then the proportion that are less than 600 and at least 100 would be 0.789

Answer:
Step-by-step explanation:
2x² - 3x - 12 = 0
Using the quadratic formula which is
From the question
a = 2 , b = - 3 , c = - 12
So we have
Separate the solutions
We have the final answer as
